Impact of nitrogen oxide pollution on health.Nitrogen dioxide is an air pollutant produced in the combustion process. When nitrogen dioxide is present, nitrogen oxides are also found; combination of NO and NO2 are collectively referred to nitrogen oxides (NOx).

At very high concentrations, which may be experienced only on fatal industrial accidents, exposure to NO2 can cause lung damage is heavy and fast. The influence of health may also occur at ambient concentrations are much lower as in the observation during the pollution incident in the city. Evidence obtained suggests that the distribution of ambient may result from chronic and acute effects, especially in the sub-population groups of people affected by asthma.

NO2 mainly behave as oxidizing agents that may damage the cell membranes and proteins. At high concentrations, the channel will air causes an acute inflammation. Moreover, the spread in short-time effect on increased risk of respiratory tract infections. Although many of controlling the spread is done, the facts clearly defines the relationship between the concentration or dose and their feedback is not enough.

To spread the acute, only very high concentrations (> 1880 mg/m3, 1 ppm) affect the health of people; when, people with asthma or lung disease are more vulnerable to acute lower concentrations.
